Koji vs. Zonka Feedback: AI Interviews vs. Multi-Channel CX Surveys (2026)

Quick Answer

Zonka Feedback is a multi-channel CX survey platform for measuring NPS, CSAT, and CES across email, SMS, WhatsApp, web, in-app, and kiosk; Koji is an AI-native research platform that runs adaptive conversational interviews and analyzes them automatically. If you need to distribute metric-driven surveys across many touchpoints and roll them into CX dashboards, Zonka is purpose-built for that. If you need to understand why your NPS moved — with AI follow-up questions, voice interviews, and automatic root-cause analysis — Koji goes deeper per respondent. The two are complementary: Zonka is excellent for continuous CX measurement, and Koji is excellent for the discovery interviews that explain the trend.

The distinction is measurement vs. understanding. Zonka tells you the score. Koji tells you the story behind the score.

What each tool is

Zonka Feedback is an AI-powered customer feedback and intelligence platform. It captures structured feedback via surveys across a wide range of channels (email, SMS, WhatsApp, web, in-app, kiosks, and offline), specializing in the classic CX metrics — Net Promoter Score, Customer Satisfaction, and Customer Effort Score. Its AI Feedback Intelligence layer unifies data from surveys, tickets, and reviews to surface sentiment and themes, and it integrates with 50+ platforms including Salesforce, HubSpot, Intercom, and Zendesk. Feedback management plans start around $199/month, with the AI Intelligence tier starting around $999/month. It''s trusted by enterprise brands for high-volume CX programs.

Koji is an AI customer research platform. Instead of pushing a static rating survey, Koji deploys an AI interviewer that holds a real conversation with each participant — asking your questions, probing every interesting answer with follow-ups, and capturing both structured scores and qualitative reasoning. Interviews run over voice or text with no human moderator. When they''re done, Koji codes the transcripts, clusters themes across everyone, and produces a shareable report automatically.

Head-to-head comparison

Where Zonka Feedback wins

• Channel breadth for measurement. If you need to intercept customers on SMS, WhatsApp, a kiosk, or offline at a physical location, Zonka''s channel coverage is broad and mature.
• Continuous CX programs. For always-on NPS/CSAT/CES tracking with trend dashboards and alerting, Zonka is built exactly for that operational rhythm.
• Enterprise CX integrations. Deep connectors into Salesforce, Zendesk, Intercom, and HubSpot make it easy to attach feedback to CRM and support records.
• High-volume, low-touch feedback. When you want one-tap ratings from thousands of customers after a transaction, a lightweight survey is the right instrument.

Zonka is a strong measurement system. Its limit is depth: even with an AI intelligence layer analyzing comments after the fact, the underlying data is still one-shot survey answers. No one asked the customer a follow-up in the moment.

Where Koji wins

• AI follow-up questions in real time. This is the defining gap. A Zonka NPS survey collects a score and maybe a comment. Koji''s AI reads the answer and immediately probes: "You rated us a 6 — what would have made it a 9?" That in-the-moment follow-up is where genuine insight lives, and static surveys structurally can''t do it.
• Voice interviews, no moderator. Koji conducts natural voice conversations. Customers who''d never type a paragraph will happily talk for two minutes, producing far richer, more candid feedback — with zero scheduling or moderation overhead.
• Root-cause analysis, automatically. Koji doesn''t just tag sentiment on isolated comments; it performs two-cycle qualitative coding — labeling themes grounded in verbatim quotes, then clustering them into a canonical codebook across all interviews. You get a defensible narrative of why, not just a word cloud.
• Discovery, not just tracking. Zonka excels at measuring known metrics. Koji excels at open exploration — the interviews that reveal problems and opportunities you didn''t know to put on a survey.
• 10x faster synthesis. Because coding and reporting are automatic, the leap from "last interview" to "insight in front of stakeholders" is minutes, not the days a manual qualitative analysis would take.

Structured questions: metrics without losing depth

Teams often adopt a tool like Zonka because they need hard numbers — NPS, CSAT, CES. Koji captures those too, without giving up conversational depth, through structured questions. Koji supports six structured question types inside one interview:

1. open_ended — free-form answers with AI follow-up probing
2. scale — numeric ratings (NPS 0–10, CSAT 1–5, effort scales)
3. single_choice — pick one option
4. multiple_choice — pick several options
5. ranking — order items by preference
6. yes_no — simple binary questions

So you can ask the exact NPS question you''d run in Zonka — as a scale question — and then let Koji''s AI anchor on the score and ask what would move it, all in the same session. You get the chartable metric and the reason, in one flow. See the structured questions guide for details.

When to use each (or both)

• Use Zonka for high-volume, always-on CX measurement across many channels, especially when feedback must attach to CRM/support records.
• Use Koji for discovery interviews, churn and win-loss deep dives, concept testing, and any time you need to understand motivation rather than just track a number.
• Use both in sequence: run your Zonka NPS program to detect movement, then send detractors or a sample of respondents into a Koji AI interview to explain it. Zonka finds the "what changed"; Koji finds the "why," and turns it into a report your team can act on this week.

Which should you choose?

If your mandate is operational CX metrics across many touchpoints, Zonka Feedback is a capable, enterprise-ready measurement platform. If your mandate is understanding customers — the reasons, the emotions, the unmet needs behind the scores — Koji delivers interview-grade depth at survey-like scale, with AI follow-ups, voice, and automatic analysis that no static survey tool can match. For product, UX, and research teams, Koji converts feedback into decisions faster and with far less manual work.
